  Fly ash contents several macro and micro nutrients which are beneficial to plants growth. It also affects to nematodes. In this book, the potential of fly ash to manage the root - knot nematodes problem on vegetable crops has been described in great detail. The soil application of fly ash with 20% is very beneficial for the crops. Additional Physical Format: Online version: Morgan, R.E. Utilization of fly ash. [Washington]: U.S. Dept. of Interior, Bureau of Mines, (OCoLC) The current percentage of utilization of fly ash in India is very less as compared to the other countries like Germany, Netherlands etc where the utilization is above 90 %. As nearly 73% of the country’s total installed power generation capacity is thermal of which coal-based generation is 90%.   Kamal J., Mishra U.K. () Fly Ash Utilization in Lightweight Aggregates for Sustainable Construction.

Fly ash is a by-product, obtained mainly from thermal power plants, composed of silicon dioxide (SiO 2) and aluminum oxide (Al 2 O 3).Other oxides present in fly ash include iron (III) oxide (Fe 2 O 3), calcium oxide (CaO), magnesium oxide (MgO) and so may also contain some trace elements such as arsenic (As), zinc (Zn), lead (Pb), selenium (Se), gallium (Ga) and germanium (Ge) and some. Keywords: Fly Ash, coal-based thermal power plants, disposal of Fly Ash, utilization of Fly Ash, waste material, resource material, environment I. INTRODUCTION Coal-based thermal power plants have been a major source of power ge neration in India where about 57% of the total.   In this paper, the utilization of fly ash in construction, as a low-cost adsorbent for the removal of organic compounds, flue gas and metals, light weight aggregate, mine back fill, road sub-base, and zeolite synthesis is discussed. % fly ash as a waste product. Present generation of fly ash from coal based thermal power plants in India is MT/year and it is expected to increase to MT/year by The current utilization of fly ash is only about 55%, mainly in the areas .

Fly ash could also be an effective amendment in neutralizing soil acidity. Many of the observed chemical and biological effects of fly ash applications to soils resulted from the increased activities of Ca 2+ and OH − ions. Most unweathered fly ashes, especially those coming from the subbituminous and lignite coals of the western U.S., are. utilization of fly ash in concrete began (for example, USBR ) follow-ing the pioneering research conducted at the University of California, Berkeley (Davis ).The last 50 years has seen the use of fly ash in concrete grow dramatically with close to 15 million tons used in con-. However, fly ash can be converted into valuable and useful product if properly utilized and many researches has been carried out in aim to increase the utilization of fly ash in various sectors especially in construction sector. In line with current economic conditions, all construction works required cost efficient with good quality of work. fly ash that is a major problem of disposal of fly ash in India. The current utilization of fly ash is only about 55%, mainly in the areas of cement as well as concrete manufacturing and building products and to some extent in earth fills.
